how to hook up u360 to 5 volt power supply
Hogie1418:
yeah when the connector came off it took a few of the little silver pieces of the pcb with it. So I am not sure if fixing it is even an option. I was going to buy a new pcb but Andy is on vacation till the 12th and I have not seen anyone else who sells the replacement part. Kinda just looking for a quick fix until I can fix it the right way by replacing it. Thanks for the response

Looks like a great start.

First step: Check the remaining stubs where the port was attached to be sure nothing is shorted across the terminals. Can't quite tell from this picture.

What I didnt realize was I was going to need a power source since my usb was busted.
I then connected the wires as ultimarc instructed
I then took an old usb printer cable and cut it and spliced the red and black wires and connected them to the ground and 5 volt wires on the harness. I then crossed my fingers and hoped for the best.

Second thing to check:
Disconnect the USB red and black wires from the U360--with no power applied, of course.
Set your multimeter to DC Volts, plug in the hacked USB cable and verify that the red is indeed +5v. Measure with the "-" lead connected to the PC case ground.
Next, verify that the black is indeed ground. (0v) Measure with the "-" lead connected to the PC case ground.
If both of those are correct, connect red to "+" and black to "-" and you should read +5v.
If you want to be absolutely certain, here is a pinout for the USB connector. (Right side, scroll down a bit.)
With no power applied, set your multimeter to Ohms and verify that pins 1 and 4 are not shorting to any other pins.
This should get you started. Let us know how it comes out.

I only saw the one way to connect to the ipac. I must be missing something on the site.

Table about I/O port and USB located 1/3rd of the way down this page.
Wasn't sure from your earlier posts if you were trying to jumper onto the remnants of the broken port (2nd option.)

Sounds like you tore a couple pads off the board. Someone who's good at soldering can generally repair it fairly easily, but such a repair is probably out of reach of someone who doesn't have a reasonable degree of practice.

Alright, when you say check to be sure nothing is shorted, how does one determine if it is shorted or not. Again, sorry, totally new to all this.

Is there any other way to determine that black is truely ground in this situation? I do not have a multimeter at this time (This is why you do not let people borrow your stuff). So at the moment I have no way to check any of that. Is there anything else we can try without this information?
